## Findings

- **warn** Annotations that disagree with the tool in `validate_project` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "validate_project" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"openWorldHint":false}; The name "validate_project" says "validate": a word for reading.
```

- **warn** Base64 strings in `create_promo` ([base64-blob](https://anlyon.dev/methodology#base64-blob))

```untrusted-server-text
The input schema at properties.scenes.items.anyOf[1].properties.color.$ref contains a 49-character base64 string.

inputSchema.properties.scenes.items.anyOf[1].properties.color.$ref: "#/properties/scenes/items/anyOf/0/properties/color"
```

- **warn** Base64 strings in `create_promo` ([base64-blob](https://anlyon.dev/methodology#base64-blob))

```untrusted-server-text
The input schema at properties.scenes.items.anyOf[1].properties.duration.$ref contains a 52-character base64 string.

inputSchema.properties.scenes.items.anyOf[1].properties.duration.$ref: "#/properties/scenes/items/anyOf/0/properties/duration"
```

- **warn** Base64 strings in `create_promo` ([base64-blob](https://anlyon.dev/methodology#base64-blob))

```untrusted-server-text
The input schema at properties.scenes.items.anyOf[2].properties.color.$ref contains a 49-character base64 string.

inputSchema.properties.scenes.items.anyOf[2].properties.color.$ref: "#/properties/scenes/items/anyOf/0/properties/color"
```

- **warn** Annotations that disagree with the tool in `ingest_asset` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "ingest_asset" as not read-only (readOnlyHint: false), and its words say it reads.

annotations: {"readOnlyHint":false,"destructiveHint":false,"openWorldHint":true}; The description's first verb is "fetch": a word for reading.
```


## Deletes or cancels (4)

Removes, cancels or revokes something. Claude Code: deny.

### `create_promo`

- The name "create_promo" says "create": a word for a change.
- The server marks it destructive (destructiveHint: true).
- Findings: warn base64-blob, warn base64-blob, warn base64-blob

Description, as the server wrote it:

```untrusted-server-text
Assemble a designed-looking promo/intro/product/data video from the Clipkit pattern library: give an ordered list of SCENES and the words, and it bakes in the camera, glass, lighting, motion blur, timing, and layout, then returns an editor link. This is a FAST option when a conventional promo structure fits — it is NOT the only way to make a video and NOT a default; for anything specific or original, author the JSON yourself and call set_project (the full creative range). When you do use this, MIX scene types to fit the brief and vary the structure — a video can be a single kinetic headline, three title cards, a showcase montage, or a data explainer; you do NOT need a hero or a cta. Scene types: hero (glass-orb logo reveal: wordmark, tagline?), kinetic (letter-fly headline: text, subtitle?), showcase (a screenshot tilted in 3D: screenshot URL), title (full-frame title card: headline, kicker?, subtitle?), cta (closing card with a glass button: wordmark, tagline?, cta), stats (hero numbers: stats[{label,current,previous?}], title?), bars (bar chart: bars[{label,value,previous?}], title?), ranking (top-N list: items[{label,value}], title?), pie (pie cards: cards[{label,value,total,previous?}], title?). The data scenes (stats/bars/ranking/pie) look best with theme "mux".
```

### `delete_element`

- The name "delete_element" says "delete": a word for removing or ending something.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Delete the element with the given id, anywhere in the tree (including one nested inside a group or its mask) — a tweak to an existing composition. (The project must keep at least one top-level element.)
```

### `load_project`

- The description's first verb is "import": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Import a previously shared project as the current project, by its share id or its editor URL (e.g. https://clipkit.dev/editor?id=…), returning its project_id. Use this to continue working on a project the user opened in the editor or shared earlier — the round-trip for open_in_editor. Pass an existing project_id to load into that project; omit it to load into a new one.
```

### `set_project`

- The name "set_project" says "set": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Replace the entire project with the given source JSON, returning its project_id. This is the PRIMARY way to build: use it to create a composition or to add/change many elements at once. (To tweak a single element in an existing project, use edit_element / add_element / delete_element instead.) REVISION RULE: if you are iterating on a video that already exists in this conversation — the user asked for changes, you are fixing your own work — you MUST pass its project_id so the project is updated in place and keeps one editor link and its version history. Omitting project_id creates a NEW, unrelated project and strands the old one; only omit for a genuinely different video. The input is validated against the @clipkit/protocol before being accepted; invalid inputs return an error. Shape: { width, height, duration, frame_rate, output_format, background_color?, defaults? (house easing, e.g. a spring), fonts?, camera?, lights?, elements:[…] }; every element has a `type` plus base fields (id, layer, x, y, width, height, time, duration, opacity, rotation, animations, keyframe_animations) and type-specific fields. CKP/1.1: keyframe easings accept a spring object {type:"spring", duration?, bounce?}; channels take stagger {each, from, ease, split, seed} to spread across text units / set copies / group children; groups take layout {direction, gap, align} (stack — no hand-computed positions); text takes a count-up {expr, format}. For exact field names + types call get_schema (optionally with an element_type) — the runtime ignores unrecognized keys, and this tool flags any it does not recognize.
```

## Changes things (6)

Creates or changes something that can be changed back. Claude Code: ask.

### `add_element`

- The name "add_element" says "add": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Append a single element to an existing project — a TWEAK, e.g. dropping in one more caption or shape. By default it is added at the top level; pass parent_id to add it INTO a group (nested). The element is any valid schema element: video, image, text, shape, audio, group, caption, or particles. To create a composition or add several elements at once, build the JSON and use set_project instead. The new element is validated as part of the project as a whole before being added. Call get_schema(element_type) for the exact per-type fields; unrecognized keys are flagged.
```

### `create_project`

- The name "create_project" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Create a new, blank Clipkit project with the given dimensions and duration, and return its project_id. Defaults: 1920×1080, 10 seconds, 30 fps, output_format "mp4". Call this first when starting a new video. Pass an existing project_id to reset that project to blank; omit it to start a fresh project (note the returned id for subsequent tools).
```

### `edit_element`

- The name "edit_element" says "edit": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Change fields on the element with the given id by merging in a partial element — only the keys you include change. The id may be any element ANYWHERE in the tree, including one nested inside a group (or its mask). Pass a whole nested value (e.g. a new `keyframe_animations` array) to replace that key; set a key to null to remove it. This is for TWEAKING an existing composition. To create a composition or change many elements at once, edit the JSON and call set_project instead. The result is re-validated before being accepted.
```

### `ingest_asset`

- The description's first verb is "fetch": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Fetch a remote media URL (image/video/audio) and HOST it on Clipkit, returning a stable asset_url to put in an element's `url`. Use this so the project's media survives — the original link may rot, be private, or block hotlinking. Anonymous projects allow up to 5 hosted assets / 100 MB total / 50 MB per file; when the limit is hit, tell the user to open the project (open_in_editor) and sign in to add more. Requires project_id.
```

### `open_in_editor`

- The name "open_in_editor" says "open": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Validate the current project and create a link that opens it in the Clipkit web editor, where the user can preview and refine it. This shares the PROJECT (nothing is rendered — that's render_video). Use after composing or editing. Returns a URL.
```

### `validate_project`

- The name "validate_project" says "validate": a word for reading.
- The description's first verb is "run": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Run the @clipkit/protocol validator against the current project AND surface render-time warnings even when the JSON is valid — things that pass the schema but the runtime will silently drop or clip: emoji / non-ASCII text (the runtime font atlas is ASCII-only), elements that run past the composition end, a missing top-level duration. Run it before you share or render the project. For a fuller timeline read-back, use describe_project.
```

## Only reads (5)

Looks things up and changes nothing. Claude Code: allow.

### `describe_project`

- The name "describe_project" says "describe": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Return a compact, human-readable summary of the current project — dimensions, fps, duration, an element breakdown by type, a per-track timeline (paint order low→high), and render-time warnings. Much cheaper to read than get_project's full JSON; use it to orient yourself or sanity-check structure without dumping the whole source.
```

### `get_project`

- The name "get_project" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Return the full current Clipkit source as JSON. Use this to inspect the project, pass it to a render pipeline, or compose follow-up edits.
```

### `get_schema`

- The name "get_schema" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Return the authoritative JSON Schema for a Clipkit Source — exact field names, types, and enums, generated from the protocol. Call with no argument for the full Source schema, or with element_type (e.g. "text", "shape", "particles") for just that element's fields (much smaller). Use this when authoring with set_project / add_element so you never guess a field.
```

### `preview_still`

- The name "preview_still" says "preview": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Render a single frame of the current project to a PNG and return it as an image you can look at. This is how you check your work — in chat there is no other way to see what a composition actually looks like. Use it liberally: after composing, after edits, and at different times to inspect motion. Stills are FREE (credits are only spent by render_video). Pass `time` (seconds) to choose the frame; defaults to 0.
```

### `read_docs`

- The name "read_docs" says "read": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Return a canonical Clipkit doc as text. topic "card" = the ~8KB compact authoring card — the recommended context for authoring; "pattern-lighting" = the shine/neon/glow technique rigs; "pattern-data-viz" / "pattern-cinematic-ui" / "pattern-ui-screencast" / "pattern-promo-teaser" = ~4-5KB pattern cards (proven idioms: count-ups and bar rows; product hero shots with camera rigs; faked app UI with typing/cursor/clicks) — load ONE alongside the card when the brief matches its archetype; "agents" = the full authoring guide (fetch only when the card doesn't cover a need); "protocol" = the formal field spec; "brand" = brand reference. (Same docs offered as MCP resources, exposed as a tool so you can read them directly — resources are not always model-readable.)
```
